Abstract: Digital village construction and rural common prosperity are the new propositions for highquality development empowered by digitalization in the new era. Digital villages serve as a new engine for advancing digital China and modernization, as well as a new driving force for promoting high-quality development of rural common prosperity. This paper reconstructed indicators to measure rural common prosperity, digital rural areas, and digital twin, and based on the panel data from 30 provincial-level regions in China from 2014 to 2021, explored the common prosperity effect of digital village construction and the moderating effect of digital twins. The research showed that: (1) Digital village construction significantly drives rural common prosperity, mainly through the digitization of rural infrastructure, economic activities, governance, and residents′ daily life; (2) The driving effect of digital village construction on rural common prosperity is influenced by digital twin, mainly through the digitization of rural infrastructure, economic activities, and governance; (3) The heterogeneity analysis revealed that digital village construction has a stronger common prosperity effect on economically underdeveloped areas, and the moderating effect of digital twin varies significantly in regions at different levels of development. Further threshold analysis showed that, for rural common prosperity, digital village construction has its own single threshold effect and double threshold effect of digital twin. The above conclusion has important implications for the realization of rural common prosperity and leapfrog development, as well as advancing Chinese modernization. It will also provide valuable references for building a digital village ecosystem in the region and carrying out policy options empowered by the digital twin.

Key words: digital village construction, rural common prosperity, digital twin
